We did the following upgrades:
Nintex workflow 126.96.36.199 to Nintex workflow 188.8.131.52
Nintex form 184.108.40.206 to Nintex form 220.127.116.11
and we followed all upgrade instructions but we have the following problem:
All old running workflows are stuck, if someone answered a task the workflow does not continue to next task.
After investigating the problems, it seems all workflows that contain loops or state machine has this problem, so the workflows are stuck in their loops without showing any error or proceeding to next tasks
Thank you for your help.
